A bright X-ray source in a massive star cluster in the outskirts of 6dFGS gJ215022.2-055059, a barred lenticular galaxy located about 806 million light-years away from Earth, is an intermediate-mass black hole, according to a new study published in the Astrophysical Journal Letters.
In 2015, astronomers found something weird. It was a white dwarf star, 570 light-years from Earth, with a peculiar dimming pattern. It dimmed several times to varying depths, each depth repeating on a 4.5 to 5-hour timeframe; and its atmosphere was polluted with elements usually found in rocky exoplanets.
Mars. Water. You’d never find two more unlikely companions, even in a buddy cop movie. But once upon a time, the dry, red dustbowl of Mars was lush and soggy.
It will launch aboard the Perseverance rover.
Mars is a pretty wild and wonderful place, and an image posted to the NASA science blog and Astronomy Photo of the Day this week is a brilliant example. It shows what appears to be a mountain… but completely hollowed out.
